Enjoy your music wirelessly from nearly any device with the anthracite grey Vifa Stockholm Wireless Speaker. The speaker has two 1.1″ tweeters, two 3.1″ midrange drivers, four 3.9″ flat sandwich-cone drivers mounted mechanically back-to-back in a force-balanced configuration, and four 2.4 x 5.5″ passive radiators to fill your room with sound. It features built-in Bluetooth with aptX, AirPlay, Wi-Fi with Wi-Di, and DLNA connectivity for near-universal compatibility. Your wired components can connect via the optical / 1/8″ combo input. If you’d like to hardwire your iOS device, you can do so via the USB port. The speaker includes an 1/8″ cable and a wall bracket.
